The philosopher's argument was logically _______, with each premise carefully supported and each conclusion following necessarily from what preceded it, yet critics questioned whether the initial assumptions themselves were defensible.
Which choice completes the text with the most logical and precise word or phrase?
flawed
rigorous
emotional
brief
Correct Answer: B
Choice B is the best answer. The passage describes "carefully supported" premises with conclusions "following necessarily." "Rigorous" means extremely thorough and accurate, fitting this logical precision.
Choice A is incorrect because "flawed" contradicts the structural soundness described. Choice C is incorrect because "emotional" contradicts logical necessity. Choice D is incorrect because "brief" refers to length, not logical quality.
